确定了氙和聚醚型配体之间形成稳定配合物的过程。通过129Xe NMR滴定、NMR扩散和异核NOE测量研究了配位过程。所研究的配体与Xe(0)形成1:1配合物。它们的稳定常数取决于配体结构,即聚醚链长度,配合聚醚单元数以及定位中心的拓扑结构。
Formation of stable complexes between xenon and podand polyoxyethylene ligands was ascertained. The complexation process was studied by 129Xe NMR titration, NMR diffusiometry and heteronuclear NOE measurements. The ligands studied form a 1:1 complexes with Xe(0). Their stability constants depend on the ligand structure, i.e., polyoxyethylene chain length, number of complexating polyether units and the topology of the anchoring centre.
